The Perimeter Institute for Theoretical Physics is celebrating their 10th anniversary with an 11 day science festival called Quantum2Cosmos: Ideas for the Future. Speakers from around the world will be converging on Waterloo, Canada to talk about string theory, quantum computation, dark matter—and a few bright green themes. Two WorldChanging Canada writers, Karl Schroeder, and Mark Tovey, are among them.

Karl Schroeder was a panellist on the 'Are We Bound for Space' panel on Tuesday at 8PM. Other panellists included Chris Hadfield, Robert Richards, Donna Shirley, and Lawrence Krauss. The session was moderated by Steve Paikin. Karl suggests, among other things, that solving the problems of living in space will teach us a great deal about how to live within one earth, instead of three. That session was broadcast live on TVO, and you can watch the broadcast here. For more background on Karl's ideas on the subject, see his WC Canada article, Colonizing Planet Earth.

WorldChanging Canada Editor Mark Tovey, will be sitting on a Science in the Pub panel on Friday 23rd at 7PM. Their converation will explore our brain, memory, and who we are, and will also include Larry Abbott and Jody Culham. It will be hosted by COSMOS Magazine editor Wilson da Silva, and will be recorded for podcast.

Some of the events with worldchanging themes will be streamed live to the internet:
